Answer:
10 days
Step-by-step explanation:
Work done by a in 24 days = 1
Work done by a in 1 day = 1/24
Work done by b in 30 days = 1
Work done by b in 1 day = 1/30
Work done by c in 40 days = 1
Work done by c in 1 day = 1/40
Work done by a, b, c in 1 day = 1/24 + 1/30 + 1/40 = 12/120 = 1/10
Total work to be done = 1
No. of days required = 1 = 10
1/10
